I realize I was running an old MPL. Hmm...how does MPL define major releases? I didn't think there would be API or functionality breakage going from 0.91 to 0.98. So, does that mean if I update my program to run with 0.98, it will no longer work correctly under 0.91? > > P.S.

For those who care, here it is, but I haven't been able to track down what's causing it, other than somewhere along the line my start/end points are getting set to inf and my code isn't doing it.
